Question

This is driving me crazy, what is the reason this doesn’t work?

var name = data.match(/first-([A-Za-z0-9-]+)/g).replace('first-', '');

I want to replace first-joe with joe.

I also tried

var name = data.match(/first-([A-Za-z0-9-]+)/g);
var name = name.replace('first-', '');

and that doesn’t work.

However the when alerting name I get first-joe

What is the reason for this, and how do I fix it?

Thanks

Answer 1

match with /g returns an array of matches (excluding parenthesized substrings), so you would have to replace them individually. If you know there is exactly one match, use data.match(/first-([A-Za-z0-9-]+)/)[1] which extracts the parenthesized substring.
